I have a few questions which all tie together. First off, I have a 1TB external hard drive which I have partitioned (effectively giving me 500 GB of space) On that same external hard drive, I have almost 500 GB of video giving me very little free space. I am deathly afraid of losing my videos so I'm curious as to what the best method of backing up my videos would be. I have a brand new iMac with an internal hard drive of 1TB. My thought was to import all my videos from my external hard drive and put them onto the internal hard drive. After that, I would de-partition my external hard drive. From there, I would use my external hard drive as Time Machine thereby effectively backing up not only my computer but the videos as well. A) Will this work? B) Can I edit videos from the external hard drive while it's acting as Time Machine? C) Is it a bad thing to edit from the internal hard drive? I really appreciate any help you can give me. Thanks in advance.
